Is port 22347 dangerous?

We have no specific security note for port 22347. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 22347, and is it reachable?

Linux

sudo ss -ltnup 'sport = :22347'      # process listening on 22347
sudo lsof -nP -i :22347

macOS

sudo lsof -nP -i :22347

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 22347 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 22347
netstat -ano | findstr :22347

From another machine

nmap -p 22347 -sV <host>
sudo nmap -sU -p 22347 <host>
nc -zv <host> 22347

Block it in the firewall

sudo ufw deny 22347/tcp                                         # Linux (ufw)

04 FAQ
What is port 22347 used for?

Port 22347 is assigned by IANA to wibukey (WibuKey Standard WkLan).

Is port 22347 TCP or UDP?

Port 22347 is registered for TCP and UDP.

Is it safe to open port 22347?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 22347 is open?

On Linux run "ss -ltnup 'sport = :22347'", on macOS "lsof -nP -i :22347", and on Windows "netstat -ano | findstr :22347" to see the local process. From another machine, "nmap -p 22347 <host>" shows whether it is reachable.
